"Since this cup of coffee was served until now, you've touched your ear three times unintentionally, your gaze has fallen on the coffee cup five times, and when talking to me, your eyes looked to the left three times. When I opened my mouth to drink the coffee, your breathing suddenly accelerated," Qin Jian said with narrowed eyes, "Although you're careful and have concealed your expressions well, there will always be slips. What do all these small actions indicate? You have a guilty conscience! If I'm not mistaken, you've drugged this coffee. As for what kind, you know best! You're a doctor, getting your hands on medication wouldn't be difficult."
After Qin Jian finished speaking, he abruptly stood up, "For the last time, where is the person?"
Cheng Yu sneered and said self-deprecatingly, "I thought you wouldn't notice at all! I believed my demeanor was natural enough, but I didn't expect you to still find me out."
"If you don't want others to know, don't do it yourself."
